RCS1096 incorrectly identifies/converts HasFlag logic

[qbert09]

Product and Version Used:
When running the conversion for RCS1096 it incorrectly converts the HasFlag logic. The current conversion treats composite flags as though HasFlag is identifying that any of the bits is set, where as in reality HasFlag will only return true if all bits are set.

Here is a sample program to demonstrate:

Steps to Reproduce:
given an enumeration and a variable x:

public enum MyFlags
{
    A = 1,
    B = 2,
    C = 4,
    D = 8,
    DA = D | A
}

var x = MyFlags.A | MyFlags.C;

if I apply the fix for RCS1096 and code:

if(x.HasFlag(MyFlags.A|MyFlags.C))
{
    //...
}

I get:

if((x & (MyFlags.A|MyFlags.C)) != 0)
{
    //...
}

When I would expect:

if((x & (MyFlags.A|MyFlags.C)) == (MyFlags.A|MyFlags.C))
{
    //...
}

Thanks for the report @qbert09 !
